WINDOW CONSTRUCTION.

Specification of Letters Patent.

Application filed October 20, 1913. Serial No. 796,366. 7

To all whom it may concern:

Be it known that I, FREDERICK J. WAT- KINSON, a subject of the King of Great Britain, and a resident of the town of Strathroy, in the county of Middlesex, in the Province of Ontario, Canada, have invented a new and useful vVindow Construction, of

which the following is a specification.

This invention relates to improvements in window construction, and more especially to combined window'sashes, Weights, pulleys, and weather strips.

An object of the invention is the pro;- vision in a window structure of a sliding weight performing the functions of a weather strip.

A further object is a provision in which the weights of one sash perform the function of a guide for the companion sash of the window or of the same sash when only one is employed.

A further object is to provide a structure simple and inexpensive to manufacture and which at the same time increases the weatherproof qualities of the window making the same a warmer window structure.

A still further object is the provision of a window weight which acts also as a guide and a weather strip and may be exposed to ready access for the purpose of noting and remedying any defects that may arise therein.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like numerals refer to corresponding parts throughout the several views: Figure ,1 is a front view partly in section of a two-sash window employing this improvement. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is a perspective view of one of the weather strip weight members shown broken away and a I detail view of one side of a window frame and sash adapted to receive said member, and Fig. & is a transverse sectional view taken through one side of the window frame substantially upon the line 4t of Fig. 2.

Referring in detail to the drawings, the window frame 10 is illustrated with the upper and lower sashes 11 and 12 respectively having substantially the usual outward appearance. Said sashes are slidably mounted between the outer window strip 13 andthe removable strip 1% and witn'the usual parting strip 15 positioned therebetween. Vertical T-shaped slots 16 are positioned longitudinally of the casing on each side thereof and in such a manner as to form longitudinal openings 17 registering with longitudinal grooves 18 positioned centrally in each opposite edge of the sashes.

- A weight member 19 is employed of the form shown in Fig. 3 having an oppositelyextending lug' 20 adapted to pass through the oblique slot 21 of the window casing and into the base rear portion 22 of the slot 16 when the weight 19 is positioned in place through the guiding slot 17. This positioningof the wei ht 19 within the slot 17 and with the lug in the slot portion 22 not only allows the weight to freely slide vertically within said slot with the lug restraining its removal therefrom except when brought into registry with the oblique slot 21, but an edge portion of the weight projects sutficiently to enter as closely as may be desired into the longitudinal side slot 18 of the sash, and which construction thereby provides not only a freely slidable weight member, but also a guide for the sash and a weather strip means between the sash and the window casing.

In the two sash windows as herein illustrated, each weight member 19 acts as a partial counter-balance to one of the sashes and is connected thereto by a cord 23 passing over one or more pulleys or sheaves 24. In a window structure employing but a single sash however, it will be noted that the scope of the invention includes the provision of having the weight of the single sash vertically movable within the longitudinal grooves as described, but having however, the suspending cord therefor passing over a pulley upon the window casing-and the cord being then attached to the top of the individual sash at any convenient point, as will be at once evident from the two sash structure illustrated.

It may be desired to include an easily re- 'movable metal shield 25 for covering the exposed portions of the weights and cords, and this member may be employed if desired as herein illustrated, or the same may be entirely omitted without affecting the perfect operation of the device. Saidmember 25 is of U-shaped form longitudinally positioned over the entranceslot 17 and one of the same may be resiliently retained between the parting strip 15 and each of the side strips 13 and.

14 so as to allow the weights 19 to slide with n said members and'the window sashes to slldably move over their outer faces, said members 25 being thereby positioned be I the sliding positions of the weights, and the window sashes interlocked thereby to the casing and forming a combined weight, sash guide and weather strip.

While the forms oifthe invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction withoutdeparting from the spirit and scope of the invent-ion as set forth in the appended claims.

\Vhat I claim asnew is 1. window structure comprising a casing having a slot therein, a sash slidable in said casing and having a recess in aline- In testimony whereof, I have signed in the presence of the two undersigned witnesses.
